z claim. (ci. 257-223) My invention relates to the art of heat exchangeand has as its principal object the provision of an arrangementrequiring a minimum ground space but having high heat eiiiciency andbeing convenient to a high degree.

It is a common practice in the petroleum re-A lining trade to dischargethe highly heated iluid from a tube type heating coil into atalllseparating and/or vaporizing chamber and to conduct the vapors fromsuch chamber to a heat exchanger in which the heat of the vapors istransmitted to a considerable extent ing toward the heating coil. Inapparatus within my invention, the separating and/or vaporizing lchambermay be combined with the heat exchange elements in such manner that onlyone foundation is required and no additional ground space need be usedover that above the separating chamber itself. Also, the heat exchangeelego ments may be readily inspected and ,cleaned when required.

Inlorder that my invention, together with its objects and advantages maybe readily and fully understood, I will now describe by way of exampleand in connection with the accompanying drawings ai combined separatingand/or vaporizing chamber and heat exchanger in accordance with myinvention and selected from a number of possible embodimentsA thereof.In the drawings,

Fig. 1 is anelevation, parts being broken away,

of an apparatus within my invention.

Fig. 2 is a plan View oi' a header ring appearing in Fig. 1. 3

through thegcen- Fig. 3 isa transverse section f ter of the ring shownin Fig. 2.

In the installation illustrated in Iiig.'y l, the separating andvaporizing chamber i0- has inlet i2 in its lower end which connects withthe discharge of a heating or cracking still of the coil or other type.Mingled vapors and/or liquids of high temperature enter the chamber IIIfrom the coil. Within chamber I 6 the pressure is somewhat reduced andthe vapors rise to the top of the chamber while the, liquids are takenoi! through outlet I4 and/or through the bottom drain i6. -A

In the arrangement illustrated, the envelope of. the chamber I 0 isextended upward in the form of a ring lila and a casing Ib within -whichare mounted a plurality of serpentine tubular liquid conducting I 6, I6,such' units being supported from the said ring. Preferably,

' there are two detachable Joints inthe envelope of. chamber Il,oneioint 2l being at the lower to raw oil mov-v edge of ring Ita and theother joint 22 between ring I 0a and casing Nb.

Ring Ilia is shown as an integral casting within which are two integralmanifold chambers 24 and 26 each oi.' which is closed at one end while 5the other end extends to the outside 0f the ring where it can.beconnected to an inlet or outlet pipe by a ilange o'r other type coupling2,6. The top walls of chambers. and 26 are drilled and countersunk toprovide passages 36, 3|! and seats 10 32, 22 whereby the ends of theumts I8 may be coupled by readily breakable joints to the walls of thechambers 24 and 26 in position to receive fluid from or discharge fluidto such chambers. Each unit I6 is formed of a zigzag tube and all 15 theunits together form a bundle through which a cooling fluid ows.

Vapors from the lower part and main part of chamber Il passup around theunits I6 to heat the liquid therein. For this purpose I have made 20-ring Ia with a wide aperture therethrough between manifold chambers 24and 26. However, any form of vapor connection between the lower portionsof chambers l0 and the portion-within casing l0b`may'be employed withinmy inven' 25 tion. In the arrangement illustrated, a horizontal baille34 is placed below a portion-of the opening. 33 through ring lila andthe gases pass up through the other half of such opening into the tubebundle formed of units I6. A vertical 30 baffle 26 extends from thebottom o f the tube bundle part way up the middle of such bundle so thatthe vapors pass around the upper edge of baille 36 and thendownwardly'through the other half ofthel tube bundle and out throughopen- 35 ing 38 in the ring Ila. However, I do not limit myself to anyparticular form of path for the vapors through the space occupied by theunits I6 and one may use a single or a multiple path arrangement withinmy invention as desired. 40 condensate formed within the casing Ilib atthe left of the central baiiie 36 drains back through4 the opening inthe ring Illa into chamber III. Such condensate as is formed within thecasing Ilb at the right of central baille 36 may vbe 45 trapped backinto the chamber III by suitable means not shown, but preferablyis`permitted to flow out with the gases through the outlet 28 so that itcan be trapped out of the line connected to such outlet at anyconvenient place.

It will be understood that chamber I0 may in practice often be eighty`or so feet high and I have shown means at the top of such chamber forliftingthe casing Illb clear of the units Il to permit inspection andcleaning of the units. Such means comprises a framework II fixed to theupper por- `tion of ing Nb. On the framework Il is a trolley-device l sothat, when joint 21 has been broken, the casing Illb can be hoisted bytackle means (not shown) and attached to trolley 4l and held out of theway above the units .I I. By such arrangement the ground space of aplant in which my invention may be use is economized to the maximumdegree. However, I do not limit myself to this in all cases. Y

It will be understood further that I do not limit myself in all cases todetails of the foregoing description, but wish the following claims tobe construed as broadly as their terms of the art permits.

the chamber and extending above the casand the me What I claim is:

1. The combination in bose ring having a wide side opening, a casing onsaid ring, a tube bundle supported from said ring and extending intosaid casing, connections whereby one fluid may pass through said bundleand baiilinl means whereby another fluid passing throughtureinsaidringmaypassover out through said side ope 2. The combinationas set forth in claim l and in which the ring has header chamberstherein on opposite' sides of its central opening.
